July 29, 2021 Second Quarter 2021 Financial Results

1 Statements contained in this presentation about future performance, including, without limitation, operating results, capital expenditures, rate base growth, dividend policy, financial outlook, and other statements that are not purely historical, are forward-looking statements. These forward-looking statements reflect our current expectations; however, such statements involve risks and uncertainties. Actual results could differ materially from current expectations. These forward-looking statements represent our expectations only as of the date of this presentation, and Edison International assumes no duty to update them to reflect new information, events or circumstances. Important factors that could cause different results include, but are not limited to the: • ability of SCE to recover its costs through regulated rates, including uninsured wildfire-related and debris flow-related costs, costs incurred to mitigate the risk of utility equipment causing future wildfires, costs incurred to implement SCE's new customer service system and costs incurred as a result of the COVID-19 pandemic; • ability of SCE to implement its Wildfire Mitigation Plan; • risks of regulatory or legislative restrictions that would limit SCE’s ability to implement Public Safety Power Shutoff (“PSPS”) when conditions warrant or would otherwise limit SCE’s operational PSPS practices; • risks associated with implementing PSPS, including regulatory fines and penalties, claims for damages and reputational harm; • ability of SCE to maintain a valid safety certification; • ability to obtain sufficient insurance at a reasonable cost, including insurance relating to SCE's nuclear facilities and wildfire-related claims, and to recover the costs of such insurance or, in the event liabilities exceed insured amounts, the ability to recover uninsured losses from customers or other parties; • extreme weather-related incidents (including events caused, or exacerbated, by climate change, such as wildfires, debris flows, droughts, high wind events and extreme heat events) and other natural disasters (such as earthquakes), which could cause, among other things, public safety issues, property damage, operational issues (such as rotating outages and issues due to damaged infrastructure), PSPS activations and unanticipated costs; • risks associated with California Assembly Bill 1054 (“AB 1054”) effectively mitigating the significant risk faced by California investor-owned utilities related to liability for damages arising from catastrophic wildfires where utility facilities are alleged to be a substantial cause, including the longevity of the Wildfire Insurance Fund and the CPUC's interpretation of and actions under AB 1054, including its interpretation of the new prudency standard established under AB 1054; • ability of SCE to effectively manage its workforce, including its contract workers; • decisions and other actions by the California Public Utilities Commission, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission and other governmental authorities, including decisions and actions related to nationwide or statewide crisis, determinations of authorized rates of return or return on equity, the recoverability of wildfire-related and debris-flow-related costs, issuance of SCE's wildfire safety certification, wildfire mitigation efforts, and delays in executive, regulatory and legislative actions; • ability of Edison International or SCE to borrow funds and access bank and capital markets on reasonable terms; • risks associated with the decommissioning of San Onofre, including those related to worker and public safety, public opposition, permitting, governmental approvals, on- site storage of spent nuclear fuel, delays, contractual disputes, and cost overruns; • pandemics, such as COVID-19, and other events that cause regional, statewide, national or global disruption, which could impact, among other things, Edison International's and SCE's business, operations, cash flows, liquidity and/or financial results and cause Edison International and SCE to incur unanticipated costs; • physical security of Edison International's and SCE's critical assets and personnel and the cybersecurity of Edison International's and SCE's critical information technology systems for grid control, and business, employee and customer data; • risks associated with cost allocation resulting in higher rates for utility bundled service customers because of possible customer bypass or departure for other electricity providers such as Community Choice Aggregators (“CCA,” which are cities, counties, and certain other public agencies with the authority to generate and/or purchase electricity for their local residents and businesses) and Electric Service Providers (entities that offer electric power and ancillary services to retail customers, other than electrical corporations (like SCE) and CCAs); • risks inherent in SCE's transmission and distribution infrastructure investment program, including those related to project site identification, public opposition, environmental mitigation, construction, permitting, power curtailment costs (payments due under power contracts in the event there is insufficient transmission to enable acceptance of power delivery), changes in the California Independent System Operator’s transmission plans, and governmental approvals; and • risks associated with the operation of transmission and distribution assets and power generating facilities, including worker and public safety issues, the risk of utility assets causing or contributing to wildfires, failure, availability, efficiency, and output of equipment and facilities, and availability and cost of spare parts. Other important factors are discussed under the headings “Forward-Looking Statements”, “Risk Factors” and “Management’s Discussion and Analysis” in Edison International’s Form 10-K and other reports filed with the Securities and Exchange Commission, which are available on our website: www.edisoninvestor.com. These filings also provide additional information on historical and other factual data contained in this presentation. Forward-Looking Statements July 29, 2021

2 2021 GRC track 1: CPUC’s proposed decision supports critical investments and provides foundation through 2023 July 29, 2021 PD would support rate base growth of ~6% over GRC track 1 period2 Total company rate base2, $ in Billions 35.7 38.0 40.0 2021 2022 2023 Capex under PD-authorized levels would be $14.0 billion for 2021–2023 Total capital expenditures, $ in Billions 4.7 4.7 4.6 2021 2022 2023 1. HFRA: High Fire Risk Areas 2. Weighted-average year basis. Excludes rate base associated with ~$1.6 billion of AB 1054 excluded capital expenditures and certain projects or programs not yet approved; CSRP application for recovery was filed on July 22, 2021, and is included in rate base starting in 2022 On July 9, CPUC issued proposed decision (PD) in track 1 of SCE’s 2021 GRC, focused on balancing necessary spending on safety and reliability with affordability – Earliest CPUC can vote on PD is August 19 One of the first rate cases to consider broad range of wildfire mitigations, including large deployment of covered conductor in SCE’s HFRA1 Would authorize $6.9 billion base revenue, 90% of request Primary O&M reductions to wildfire insurance premiums and vegetation management costs; however, not expected to materially affect earnings or execution because of balancing and memo accounts for costs above authorized Proposed capital forecast reduction primarily due to reduced scope of Wildfire Covered Conductor Program, which is contrary to Commission and State public policy Would approve ~98% of non-wildfire mitigation-related capital, providing funding for safety and reliability, and continued implementation of State’s public policy goals

3 SCE’s opening comments focus on addressing covered conductor program scope and other critical issues July 29, 2021 SCE’s opening comments will note several areas that, if corrected, would result in a balanced final decision PD’s cuts to wildfire covered conductor program are inappropriate Proposes $1.86 billion, or 54%, cut to Wildfire Covered Conductor Program Based on TURN’s flawed estimation of risk, not the overall record Contrary to State policy to minimize risk of catastrophic wildfire Would deprive customers of a key risk reduction tool PD errs by not allowing for increased vegetation management labor costs Proposes reduction of ~$138 million for vegetation management costs Cost increases submitted in update testimony due to contract negotiations and SB 247, which increased labor rates PD would direct SCE to track costs above authorized in a balancing account for recovery in another proceeding PD should not make certain technical changes that reduce rate base Customer deposits excluded from rate base, contrary to other CPUC decisions, reducing test year rate base by ~$200 million Working cash assumptions at odds with established precedent, reducing test year rate base by ~$389 million PD makes erroneous reductions to compensation forecasts Calculations of incentive compensation based on flawed findings Makes incorrect characterization of regulatory goals and interpretation of Public Utilities Code

20 Edison International's earnings are prepared in accordance with generally accepted accounting principles used in the United States. Management uses core earnings (losses) internally for financial planning and for analysis of performance. Core earnings (losses) are also used when communicating with investors and analysts regarding Edison International's earnings results to facilitate comparisons of the company's performance from period to period. Core earnings (losses) are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings (losses) are defined as earnings attributable to Edison International shareholders less non-core items. Non- core items include income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as write downs, asset impairments and other income and expense related to changes in law, outcomes in tax, regulatory or legal proceedings, and exit activities, including sale of certain assets and other activities that are no longer continuing. A reconciliation of Non-GAAP information to GAAP information is included either on the slide where the information appears or on another slide referenced in this presentation.
